Check for valid paths when getVolumeList() returns invisible volumes.

The FLAG_INCLUDE_INVISIBLE was created to let SM.getStorageVolumes()
return mounted volumes (like USB drives), but in the current form it
might return invalid volumes. For example, when a SD Card is adopted as
an internal storage, it will return 2 volumes instead of one, the "bad"
one being:

VolumeInfo{emulated}:
     type=EMULATED diskId=null partGuid=null mountFlags=0 mountUserId=-1
     state=UNMOUNTED
     fsType=null fsUuid=null fsLabel=null
     path=null internalPath=null

As such, we need to filter out those volumes that don't have a path.
