Crash if regex priority is empty

[AustralEpitech]

To reproduce:

• Click on Add in the Number rules section, in Regex Settings
• Empty the field Priority
• Click Save

I guess the bug is pretty obvious, but here is the crash log:

fixed in v1.14 When it's empty, there will be an error prompt and cannot be saved.
