 Saving and loading projects can corrupt the datasourceUri for delimited
 text providers when the project is configured to use relative paths.

 The problem is that the QgsProject readPath and writePath functions assume
 that the entire Uri is a file path, and change all "\" to "/".  For the
 delimited text provider the Uri is encoded as filename?parameters.  The
 parameters can include regular expression defintion, which includes valid
 backslash characters.  These get converted to slash characters, rendering
 the regular expression incorrect.

 This is fixed by the attached patch
