Set master on development

This is not the 1.7 rc2 version and we are on development (so micro_version is
90 until the next release). Set stable as False. This should be set only when
doing the real release and not let set to True all the time.

Also, fix a wrong check on bootstrap (caught by a test). It should check for
micro_version not extra_version.
