remote: handle pushremote config in any order 

The remote we push can be defined either by
remote.pushdefault or by branch.*.pushremote for the current
branch. The order in which they appear in the config file
should not matter to precedence (which should be to prefer
the branch-specific config).

The current code parses the config linearly and uses a
single string to store both values, overwriting any
previous value. Thus, config like:

  [branch "master"]
  pushremote = foo
  [remote]
  pushdefault = bar

erroneously ends up pushing to "bar" from the master branch.

We can fix this by storing both values and resolving the
correct value after all config is read.
