`compiler-bridge-test` & `zinc-scripted` do not show up in IntelliJ

[Friendseeker]

steps

Open zinc via IntelliJ

problem

compiler-bridge-test & zinc-scripted are not properly recognized by IntelliJ.

Hence none of the smart IDE features work when editing files from compiler-bridge-test & zinc-scripted.

expectation

The two projects should are recognized by IntelliJ.

notes

This is certainly possible. In fact the following changes make IntelliJ recognize compiler-bridge-test & zinc-scripted.
