bitbake: fetch/git: Fix usehead for non-default names

Browse Source 
The usehead url parameter for git repositories causes bitbake to use
whatever commit the repository HEAD is pointing to if the repository
happens to have the name 'default'. This is the default name so in many
cases it works just fine, but if a different name is specified with the
url parameter 'name=newName' then it will fail to parse the recipe with
an error along the lines of:

ERROR: ExpansionError during parsing /path/to/my/recipe.bb

Let's fix this by setting the unresolved rev of _all_ repository names
to 'HEAD' when the usehead url parameter is specified. Update the
currently failing test, test_local_gitfetch_usehead_withname, to now
expect success.

This change preserves existing behavior that allows usehead to be
overridden by a valid looking revision if one happens to be specified
instead of AUTOREV.
