This PR switches `globWithWorkspaceContext` with
`globWithWorkspaceContextSync` for `nx init` and `nx import`, since the
latter isn't guaranteed to have updated file map during the init/import
process.
Note: Also updates Gradle import test to ensure the destination repo
does not have uncommitted changes.
<!-- If this is a particularly complex change or feature addition, you
can request a dedicated Nx release for this pull request branch. Mention
someone from the Nx team or the `@nrwl/nx-pipelines-reviewers` and they
will confirm if the PR warrants its own release for testing purposes,
and generate it for you if appropriate. -->
