[bug][5.2.42][Default mandatory field] Does not work like a text type field

[MacarenaReina]

🐞 bug report

⁉️ Describe the bug

I create a new module (when you create a new module it creates a mandatory text field too). When I edit the default field of a record from 0.4 to 0.40 it does not detect changes so it does not save the new value (0.40).

🔥 How to trigger the error

Steps to reproduce the behavior:

I think the problem is there because $this->getPreviousValue() is empty: https://github.com/YetiForceCompany/YetiForceCRM/blob/acc6528abd051703737e0fc94e071058975f9916/modules/Vtiger/models/Record.php#L462

👎 Actual Behavior

Does not save the new value

👍 Expected Behavior

Save the new value because in my case we need to write on this field text or numbers but in the case of numbers it can be with zeros at the end.

Works on gitdeveloper.

I have just test it on gitdeveloper and it does not work. If you reload the view disappear the last zero.

I think it's a problem with the use of trim in some function, because it removes final zeros too.
