This reverts commit be8ee10e35319e80200d4ff384434d46fe7783d9.
A list of dicts (as opposed to strings) is valid input as well; see the
module-level doc string for details (section 2 under CUSTOMIZATION). In
fact, the nested estimate() function in MirrorGroup.init() accounts
for that, too.
This fixes a traceback in YUM which does pass such a dict list.
