Rebecca Stambler d7101b74a4 internal/lsp: set version correctly after textDocument/didOpen
The early return logic for didOpen events in
(*snapshot).invalidateContent was preventing the creation of a new
snapshot, which was in turn stopping the versions from being updated.

This exposed a fundamental issue in the way we were calculating
workspace diagnostics. Since we weren't waiting for diagnostics to be
completed for an entire snapshot before replying that the server had
been initialized, snapshots were being cloned without any type
information. For quickfix code actions, we assume that we have all
information cached (since we need to have sent the diagnostics that the
quickfix is mapped to), so we were not finding the cached analysis
results.

To handle this in the short-term, we key analyses by their names, and
then regenerate results as-needed for code actions. This is technically
more correct than simply assuming that we have the analyses cached. In a
follow-up CL, I will send a follow-up that will make sure that
snapshots "wait" on each other to be fully constructed before being
cloned.
