Better paths sanitization

[tomasMizera]

This PR adds some enhancements to the sanitization logic:

• whitespace in individual folders/files within paths is now trimmed, e.g. / my folder / my file.ext ~> /my folder/my file.ext
• whitespace before file extension is now trimmed, e.g. /my folder/my file .ext ~> /my folder/my file.ext

These scenarios were possible because of the custom photo name formats. It then caused problems when syncing to desktop builds or server did not allows such an upload at all.

These two enhancements are used in:

• projectwizard.cpp -> sanitize project name so it does not include a whitespace at the end
• attributecontroller.cpp -> when renaming photos

Fixes #3976
Fixes #4022
Fixes (likely) #4157 - needs to be tested (cc @RastoHu @IvaKuklica) nope
See also MerginMaps/qgis-plugin#693

Qt handles path separators automatically, but would be good to test this out on Windows, just to be sure.
