[FIX] web: click on a readonly field on editedRecord

Before this commit, in a list view, if you click on a readonly field of
a record in edit mode, then it switches to readonly mode.

Why ?
The "pe-none" class added to readonly fields will prevent clicking on it.
Our click will then be applied to the table causing a unselectRecord
on the list.

How to reproduce:
- Going into an editable list view with a readonly field
- Click on a field to switch the record to edit mode
- Click on the readonly field

Before this commit
 The record switches to read mode

After this commit
 The record stays in edit mode
