Export of id-based ts files creates non-id-based qm files

In Qt Linguist you have the option to release a qm file from a ts file (File-Menu->Release).

This can be usefull in cases where non-developers are doing the translations and want to intermediate test their work without the support of a developer or extra tools.

In our case we have an id-based translation. Here we found that qm files released through qt linguist can not be loaded within our application, while using lrelease -idbased on the terminal works as expected.

After checking the source-code of qt linguist it's obvious that this code path is not implemented at all, see:

https://code.qt.io/cgit/qt/qttools.git/tree/src/linguist/linguist/messagemodel.cpp#n335

Within this code we would have expected that m_idbased of ConversionData is set to true in case that the ts file is id-based.
