backup_restore_profile.py -b fails if a folder mozilla-profile already exists

[alex-mayorga]

backup_restore_profile.py -b seems to bail out if a folder mozilla-profile already exists.

Also the WARNING should be ERROR, flash red or somehow highlight you're about to lose user data.

$ python backup_restore_profile.py -b

Due to the pvt sever was stopped, we plan to re-write the shell scripts to python and move the tools to PyPI.
Could you please help to try b2g_util 0.07 [1]?
It will detect the local folder before backup data.
