documentviewer: Fix documentviewer_de.ts fileHEADdev

0ef5057f45ccd86 did remove the local project() for
app/CMakeLists.txt. As a side-effect, update_translations
now did search _all_ source files in the project for translatable
strings, including the plugin directory.

Avoid this by being explicit about the SOURCE_TARGETS.
