Fix Scala.js tests not running plus update SBT/Scala Version

[mdedetrich]

Problem

The Scala.js tests were not running when using docker-compose run --rm sbt sbt test likely due to node changing the binary path of the installation which Scala.js couldn't detect

Solution

Update the SBT docker image to the latest version gets the Scala tests running again. It seems like the upgrade of SBT has also fixed historical memory issues with SBT, i.e.

[warn] In the last 9 seconds, 5.127 (60.2%) were spent in GC. [Heap: 0.37GB free of 1.45GB, max 1.45GB] Consider increasing the JVM heap using `-Xmx` or try a different collector, e.g. `-XX:+UseG1GC`, for better performance.
java.lang.OutOfMemoryError: Java heap space
[error] [launcher] error during sbt launcher: java.lang.OutOfMemoryError: Java heap space

No longer seems to occur on my local machine

Notes

Since the SBT docker image was updated to the latest version, I also updated the corresponding Scala versions. I have also added the coursier directory to be cached so that every test invocation doesn't need to re-download dependencies.

Note that the PR will fail to build until #2183 is merged (and I rebase this PR)

Checklist

@deusaquilus I have just rebased off master which includes #2183 so the PR should be good to merge (the tests also passed earlier when you yourself pushed master into the branch)

@deusaquilus All tests are passing

@deusaquilus I have bumped the SBT version again (a new version just came out yesterday) and rebased it again so its ready to merge.
