Translation does not work for button used within common layout

• Package version: 1.8.1
• Django version: 3.0.1
• Python version: 3.7.6
• Template pack: (Optional)

Description:

Translation does not work for button text when used within a common layout as described in the docs here. The translation does not update as it should when the language is changed.

Steps to reproduce:

• Go to this heroku app.
• Switch the language using language selection links at the bottom.
• Language updates for the whole page except for the button text.

See the source code of it here on GitHub using common layout for buttons.

Why this happens:

This happens because when BaseInput class of crispy-forms renders it converts the lazy django translation object passed as value to string and stores it back to value overwriting it here, hence the lazy translation object is lost upon the first render of the input element. If we don't overwrite the original value the issue is resolved.

This is not limited to the buttons in a common layout. The problem exists for all Buttons/Submits used in any layout.
