Fix show user info error

[chyok]

Hi,
closes: #27479

I found that this code will permanently delete the userinfoedit key in the context of the entire process
widgets['show'].template_args['actions'].pop('userinfoedit')
In fact, it will affect self.actions so the next deletion will be reported key error.

An interesting phenomenon is that when you refresh the page, there is a certain probability of success, but the number of successes will not exceed the number of your workers, because the "actions" of each process are affected.

setting a default value can solve this problem.

Yes, it is very easy to reproduce.
Security ->List Users ->show record and refresh several times will appear.
