[FIX] account: traceback on clicking journal in account dashboard

before this commit, on clicking the bank journal in ce,
is showing traceback.

traceback:
action['domain'] = (action['domain'] or []) + [('journal_id', '=', self.id)]
TypeError: can only concatenate str (not "list") to str

after this commit, on clicking no traceback wont be shown
and corresponding action will get open
