The i18n tests that QML files are always UTF-8. To do this is creates a QML file with a name that only makes sense if it is UTF-8 encoded and tries to load it from another file. This file is generated next to the other test files for the i18n tests in the source directory. The files is removed at the end of the test by some cleanup code but if the execution is interupted during the test, like during a compile-debug loop, the file is left behind and pollutes the source directory. Rework the test to utilize a temporary directory. This way any files left behind do not pollute the source. The check was initially introduced by 176698a91d3b2256a093785967c6706328981af4 Later 1ec1a863471445132c1d29500d6ac720663887ae adapted it to fix it on Android. The .qrc and .pro files it introduced or edited were later removed by 338e892a18b73c912881e6e7f93ade0dbaa1eb8b and 78ab4b8d8b75fed240cded1a3f182048e56a8823 respectively.
