Robert Findley 96d05aa120 gopls/internal/regtest: fix TestFailingDiagnosticClearingOnEdit
This test was asserting immediately on the non-presence of published
diagnostics, and therefore was racing with the diagnostics calculation
pass. Following https://go.dev/cl/420539 this became a flake, because
once gopls has calculated diagnostics for the open event, it will
actually publish empty diagnostics for the opened file.

Update the test to use a OnceMet so that we only evaluate the
expectation once we've finished the diagnostics pass. As a result, the
test deterministically failed, which was fixed by using the
EmptyOrNoDiagnostics expectation.

Fixes golang/go#54271
