[PATCH] remote-helpers: remove --graph in hg_log()

[Antoine Pelisse <apelisse@gmail.com>]

The hg_log() test helper uses the "--graph" parameter that is
implemented by the GraphLog extension. If the extension is not activated
by the user, the parameter is not available. Do not use the option that
is unnecessary.

Also changes the way we grep the output in hg_log(). The pipe operator
can hide the return code of hg command. As a matter of fact, if log
fails because it doesn't know about "--graph", it doesn't report any
failure and let's you think everything worked.

Hey Felipe,
I'm not so confident that --graph is useless to the test. If it's really
necessary, it would be nice either to activate it in setup() or to use
it just for the command through: "--config extensions.graphlog=".

Cheers,
