[FIX] Unescaped source string characters

[mmattel]

Some source strings have not been uploaded to Transifex although downloading translations passed flawless.

The root cause was, that there were TX unescaped forbidden characters in source strings.

In the translation-sync repo, things were green although an error was reported but the error did not create an exit 1 leaving the state passed. Additionally, and this was really hard to find, who looks on green pipeline console step outputs, I found the incomplete message: owncloud-android.android - failed to upload of resource 'o:owncloud-org:p:ownc.. pointing to the right direction. The text was literaly copied from drone console...

Analyzing the drone command that pushes data which is tx push -s --skip (skip is here the culprit), I used that command in the repo locally to see what the output really is. Here comes the next issue, tx needs a horizontally oversized shell window to print all the log data which is a bug. See an example:
...parse_error: You have one or more unescaped characters from the following list: ', ", @, ?, \n, \t in the string: ...

When cycling thru the strings that were reported as error, I found all issues which just needed either a removal because wrong starting/ending double quotes or just needed character escaping.

Finally, after all issues have been fixed, the tx command passed and uploaded all pending strings 😄

I double checked that strings missing are now on TX.

Note that I highly recommend an Android drone step that checks source strings for unescaped forbidden characters according the list above which would eliminate such a hard to find issue directly at the root.

Note that I just have filed a tx bug report for this console issue.
