phabsend: make --amend the default
The local tag feature was intended to make `phabsend` closer to `email`
workflow. But its experience is not great in multiple ways:
- after rebase, obsoleted changesets are still visible because of tags
- without obsstore, the association information will get lost
- even with obsstore, things could go wrong with graft, export+import
- no easy way to tell which Differential Revision a commit is associated
Therefore make `--amend` the default. People wanting the old behavior can
use `--no-amend`.
