cannot alias a factory service with inject

[ijessen-mitll]

inject cannot find services which are both aliased and factoried. For example:

class Repository: ...

@inject(alias=Repository, use_factory=True)
class PerInstanceRepository(Repository): ...

@inject
class Service:
   def __init__(self, repository: Repository): ...

Container.__getitem__ looks for factory services before resolving aliases. However, factories are not referenced again after aliases are resolved.
