PO file with long strings

SUMMARY
PO files can have their source and target strings split over multiple lines (if the string is long, for instance). Lokalize reads them as having newlines added to the strings themselves, rather than processing the PO files and stripping out those newlines

STEPS TO REPRODUCE
1. Open a simple PO file with a long untranslated source string
2. Make a change that counts as a translation of any string
3. Save the file
4. Close Lokalize
5. Reopen Lokalize and the file

OBSERVED RESULT
Both source and target strings that are long have been modified by Lokalize when saving the file, correctly formatting them for PO strings over multiple lines. But the data is not parsed properly when reading the data back, and displays with the newlines still in the strings.

EXPECTED RESULT
Correctly parse strings.

SOFTWARE/OS VERSIONS
Lokalize version: git main

Included is a simple PO file you can test with.
