extension/test/gopls: increase the stretchr test timeout

Allow more time for shutting down gopls. The stretchr
test requires 3rd party modules to build and need more
time for gopls to load & shutdown.

Remove unnecessary async in afterEach callback.
This async caused the callback to be unnecessarily wrapped
in a Promise and triggered confusing error message in case
of test failure - unresolved promise even when the cause of
failure is somewhere else.
