Jeffrey Lau e0181f8832 linter/scala/metals: Fix return value of GetProjectRoot()
It was returning 0 when it should be returning an empty string.

The 'AssertEqual' in the ale image is from an old version so it does not
check the types of the arguments.

This is already fixed in 427fe19104

Closes #3120
