Test: Add smoke tests for lsp

[spotandjake]

Currently we do not test the lsp, we cant really test the features / visual output when interacting with an editor well, but what we can do is add some basic smoke tests that test how it responds to different inputs and ensures we are providing back valid lsp commands. This would ensure that things do not break such as when we switched from the import system to the module system in v0.6 some things may have changed that could affect the lsp we want to ensure that those changes are actually being made.
