253: Fix diagnostic fixes showing up everywhere r=matklad a=flodiebold

The LSP code action request always returned the fixes for all diagnostics anywhere in the file, because of a shadowed variable.


There's no test yet; I wasn't sure where to add it. I tried adding one in `heavy_tests`, but that's a bit uncomfortable because the code action response contains the (random) file paths. I could make it work, but wanted to ask beforehand what you think.
