#2070: shallow checkouts do not work with branches

 Currently using both --shallow and a branch (rather than master) fails
 since GetComponents wants to first clone the full repo then switch to the
 requested branch which fails with a shallow clone.

 However newer versions of git (>=1.7) support a "-b" (branch) option for
 clone and that one works fine even with shallow clones.

 My recollection is that we could not use this method initially since there
 were clusters around that only offered git 1.6 (queenbee likely). This is
 no longer the case and all clusters in simfactory offer at least git 1.7.

 This pull request:


 both fixes the problem and simplifies the code.
