QGIS project translations strings send breaking strings for translation

[ponceta]

What is the bug or the crash?

As implemented in #7456

We face an issue with

• project strings with context :valuerelationvalue

Which are send to the strings for translation but are breaking the project if translated (fields are needed as they are for the project to work properly != translated strings)

Our specific case :
teksi/wastewater#480 (comment)

Steps to reproduce the issue

1. Export strings of a project with relations
2. Translate these strings
3. Open the translated project
4. Relations are broken or dysfunctional
