Merge #9301
9301: internal: Start refactoring ide_completion tests r=Veykril a=Veykril Our current completion test infra resovles around usually just checking a specific `CompletionKind` which is suboptimal. We only see what we want to see in tests with this causing us to miss a lot of incorrect completions we are doing. Instead we should test for different cursor locations for all kinds(sans the magic kind maybe? not sure yet). This way we will also see potential duplicate completions that merely different in their kind. Also since most completion submodules complete things in tests of other modules due to the tests overlapping it makes more sense to group these tests differently which implies moving them to a new module. Exceptions for this might be stuff like attribute completion as these cannot currently interfere. I only wrote a few tests to check for completions in `ItemList` position so far and I already found a few incorrect/irrelevant completions as these haven't been tested properly due to them being hidden by the `CompletionKind` filtering. I think `CompletionKind` doesn't really seem to be beneficial to me as to I can't think of a occasion where we would want to only check a specific completion kind.
