Make sure tests on different sf versions are wokring

[Nyholm]

I made a misstake in #83.
Using --no-scripts will disable flex from running. In current master we are always using latest sf version.
I wanted to run --no-scripts to avoid recipes being installed. That would add a bunch of new files that does not comply with our CS guidelines, ie build will always fail.

This PR first installs flex globally. Then install all packages to the correct (lower) version. That means no recipes are installed.

I also use environment variable instad.

It's still always pulling in 4.3.2 and ignoring the version that's being set. The second call to composer update apparently does nothing - it just outputs the "Nothing to install or update" message (from what I can see from the CI).

[Nyholm]

Yeah, Im still debugging. I think I found a solution now. I install flex globally.

Waiting on travis with suspense =)

[X-Coder264]

It still doesn't work 😛

If a working solution isn't found "soon" I'll have to revert the previous PR which broke this so that we can have a working CI for other PRs.

[Nyholm]

Hm... It works locally.. Strange. I'll keep trying for an hour or so.

[Nyholm]

Okey, I think I know that the issue was. Since composer is in the docker image it never saw my environment variable. =)

[Nyholm]

Flex is also installing packages in parallel and it supports specifying symfony versions

[Nyholm]

Wohoo. It is working now =)

Thank you for merging
