internal/lsp/fake: reflect on-disk changes in clean buffers

If an open buffer is unmodified from the on-disk version, and that
on-disk content changes, VS Code will update the buffer with the change.
This is relevant for our quick fixes that use the go command to make
changes to go.mod/sum -- we want tests to pick up the changes without
needing to close/reopen the buffer.

For whatever reason, VS Code doesn't do this for deletions, and it made
the implementation easier, so I followed suit. I also mimicked its
behavior of sending both in-memory and on-disk change notifications.
