Bodge: remove QUrl::NormalizePathSegments option that cause Travis CI fail

The reason why the Travis continuous build system does not accept this flag whereas my current Qt build system does is unclear - so take this
option - which is to remove redundant . and .. entries from QUrls that are
local paths from the string for display to a user - is not clear so take it
out until the cause can be established.
