Muir Manders e54115a062 internal/lsp: fix stuck diagnostic messages ... The "analyses" cache in lsp/cache.(*Package).GetActionGraph was not getting cleared on errors. This could result in future calls to GetActionGraph waiting on the "ready" channel indefinitely. This in turn caused the goroutine in cacheAndDiagnose to block indefinitely and never send the diagnostic results back. Now we use a defer statement to always close the channel. If we did not succeed, we also clear out the cache entry and set a "succeeded = false" flag to signal waiters that they need to retry. If in the future errors other than context.Canceled/Timeout are possible, this retry behavior may need to be revisited.
