Back out "remotenames: push anonymous head if --force is given"

Original commit changeset: 905b79d62df8

There are already two ways to do this:
* set remotenames.forcecompat = True
* set remotenames.pushanonheads = True

The backed out revision violated the expectation of someone who does not have
forcecompat = true. It also did not have any tests.
