In shouldRunGopackages we would reset a goFile's metadata and pkgs in
advance of re-running go/packages. However, if we did not end up
running go/packages for whatever reason (read: we got canceled), the
goFile gets stuck in the unfortunate state of not belonging to any
packages because "pkgs" is empty. I think this leads to "no
CheckPackageHandle" errors, at least in relation to GetCachedPackage()
calls.
Fix by deferring the reset of goFile's metadata and pkgs until after
the go/packages call has succeeded.
