[PATCH] test suite: saver check if bzr is installed

[Simon Heimberg]

On my debian system there is an (automatic generated) empty __init.py__. Probably because of a module in a subdirectory of bzrlib. Several tests fail because of this.

test suite: saver check if bzr is installed

Test if bzrlib.__doc__ is not empty. Ignores an empty lib.
