pull: use opts.get('bookmark') instead of opts['bookmark']
This is done because at places in hgsubversion, we call the function directly. I
expect there might be more instances in extensions out there which calls
commands.push() directly. So let's not require explicitly passing of bookmark
value.
The use of opts['bookmark'] was introduced in
bad05a6afdc89cc58a2af320698ab29bd8de62d4.
