[FIX] web: non-deterministic error with translation button on a list view

Since [1], an error was introduced when using the translation button on
a list view. This error occurs in a non-deterministic way. The issue
occurs because without the option stayInEdition when saving the record
before opening the translation dialog, the row is switch to readonly,
and the translation button is not opened.

This occurs in a non-deterministic way because there is a mutex in a
mutex. When switching the modes (in a save with mutex) a second save is
perform (with also a mutex), this commit will also fix this issue.
