push/outgoing: print remote target path even if there's an error (issue2561)

This is a simple patch to make hg push/hg outgoing print their remote target
path even if the operation fails. I'm not sure if the original behavior was by
design.

This patch also changes one test to reflect the changed behaviour.

# simple script to be used in hooks
#
# put something like this in the repo .hg/hgrc:
#
#     [hooks]
#     changegroup = python "$TESTDIR"/printenv.py <hookname> [exit] [output]
#
#   - <hookname> is a mandatory argument (e.g. "changegroup")
#   - [exit] is the exit code of the hook (default: 0)
#   - [output] is the name of the output file (default: use sys.stdout)
#              the file will be opened in append mode.
#
