NB: not sure if we should fix that, just logging it here so that we know

 java.io.IOException: No such file or directory at java.io.UnixFileSystem.createFileExclusively(Native Method) at java.io.File.createNewFile(File.java:1012) at ai.grakn.graql.GraqlShell.setupHistory(GraqlShell.java:474) at ai.grakn.graql.GraqlShell.executeRepl(GraqlShell.java:394) at ai.grakn.graql.GraqlShell.start(GraqlShell.java:370) at ai.grakn.graql.GraqlShell.runShell(GraqlShell.java:266) at ai.grakn.graql.GraqlShell.runShell(GraqlShell.java:170) at ai.grakn.graql.GraqlShell.main(GraqlShell.java:165) at ai.grakn.dist.DistGraql.run(DistGraql.java:52) at ai.grakn.dist.DistGraql.main(DistGraql.java:44)

I believe the cause is this:

 private static final String HISTORY_FILENAME = StandardSystemProperty.USER_HOME.value() + "/.graql-history";

If a user doesn't have a home directory it throws an exception on file creation.

I think we should catch this exception and tell the user they need to fix it (through an error message). @lolski @kasper-piskorski

@lolski @haikalpribadi tell user to fix it? what's wrong with having no home directory? shouldn't we instead make the history file optional?

@kasper-piskorski If we don't need to fix it, I don't have a problem with that, Kasper. But is it possible to make the HISTORY_FILENAME optional?

Yes, it should be possible. Shall I create a ticket for that?

Make history file optional (#16)
19fe1b2 
## What is the goal of this PR?

Fix #7
Previously, Grakn Console would crash in case history file could not be created (possible reasons are user's home directory being non-present or mounted read-only)

## What are the changes implemented in this PR?

- Bump `@graknlabs_protocol` version
- Make an adapter class which allows to `.flush()` history object regardless of whether it's backed by `FileHistory` or `MemoryHistory`
- Resort to using in-memory history in case history file could not be created

# Why is this PR needed?

Fixes typedb#5 
So we are able to use `client-nodejs` with the latest `@graknlabs_grakn_core`

# What does the PR do?

- Upgrades commit hash of `@graknlabs_grakn_core`
- Fixes the client to comply with new API

# Does it break backwards compatibility?
