Stop checking for spaces in file paths

As of R 3.5.1, spaces in file paths are not a problem anymore. Please consider removing the check for spaces in file paths.

After some more investigation, the spaces in the file paths are actually a problem for the programming language of Praat (and not for PraatR), so I'm not sure that this issue can be solved here.
