fix(core): handle multiple messages

[wSedlacek]

Current Behavior

Currently the file watcher for the @nx/js:node executor can fail to read messages when they occur too quickly (rapidly saving)
The error is

Watch error: Unexpected token  in JSON at position 157

The data it is trying to parse is

"{\"changedProjects\":[\"standard-json-schema\"],\"changedFiles\":[{\"path\":\"libs/shared/util-std-json-schema/src/lens-schema/lens-schema.util.ts\",\"type\":\"update\"}]}\u0004{\"changedProjects\":[\"standard-json-schema\"],\"changedFiles\":[{\"path\":\"libs/shared/util-std-json-schema/src/lens-schema/lens-schema.util.ts\",\"type\":\"update\"}]}\u0004{\"changedProjects\":[\"standard-json-schema\"],\"changedFiles\":[{\"path\":\"libs/shared/util-std-json-schema/src/lens-schema/lens-schema.util.ts\",\"type\":\"update\"}]}\u0004{\"changedProjects\":[\"standard-json-schema\"],\"changedFiles\":[{\"path\":\"libs/shared/util-std-json-schema/src/lens-schema/lens-schema.util.ts\",\"type\":\"update\"}]}"

This is two messages with a 0004 between.

Expected Behavior

The file watcher should not get errors when too many messages occur at once.
