PDF import with not text layer, but text import checked, leads to "correction" instead of "transcription"

[saracarl]

If folks import a PDF and check the "import text from the text layer" option, we set the project as a "correction" project, even if there is no text. We shouldn't. Can we check for text (or make sure we don't input "blank" text) before setting that?

Here's an example: https://fromthepage.com/clerkchaz/rockingham-county-minute-books

The UI ends up saying "correct" everywhere instead of "transcribe"
