Working directory is incorrect when testing via IntelliJ

[olafurpg]

Reproduce: https://github.com/olafurpg/intellij-bsp-pants/tree/working-directory

Run

./setup-bsp.sh
cd ../intellji-bsp/src/src

Testing with Bloop in terminal

Works as expected with fix from scalameta/metals#1209 (requires changing the version of metals in setup-bsp.sh)

bloop test src/test/scala/foo:foo

Testing with IntelliJ via BSP project

It may be that we need to add more information to the BSP spec in order to fix this issue 🤔
