Path not iterable when importing tesnorflow in a solution when api_version=0.6.0
Some solutions use imports, whose init files want to iterate over sys environment paths. Since in Album's API-version 0.6.0 some paths are set as Path-like objects, it can happen, that sys.path contains such Posix- / WindowsPaths that are not iterable.
This got fixed in album api version 0.6.1! But when album version 0.11.0 is installed, and a solution requests api version <0.6.0 upon installation, 0.6.0 will be installed by default, which lead to the error described above. Therefore, fixing #209 and updateing the latest known and automatically used api verison, will solve this as well.
