Source string with an empty "" at the start can't be translated

[adem4ik]

1. Open any po file with translation
2. Add "" at the start of msgid
3. Save po file and find the string ingame

Result: string won't be translated Expected result: string is translated

Examples:

msgid "" "Ready!" msgstr "Готов!"

msgid """Ready!" msgstr "Готов!"

Such kind of .po may appear after using po-normalize. At least Transifex do so with translation files. https://www.gnu.org/software/gettext/manual/html_node/Normalizing.html
