Fix checkout error when depth passed to repo init and revision is a sha1

Browse Source 
Currently, if direct fetch of a sha1 is not supported by git server and
depth option is used, we fallback on syncing the upstream branch by
ignoring depth option.

This fallback doesn't work in next 2 cases:
(1) upstream attribute is not specified in manifest
(2) depth option is passed to repo init command
    (not with clone-depth attribute in manifest)

This commit do the following:
- fixes (1) by updating condition used to apply fallback
  first we retry with depth set to None, then by syncing all branches
- fixes (2) by passing depth as argument of _RemoteFetch() method
  thus, its value is not set again to depth value passed to repo init
  command when applying fallback
