commit 42aa734475ff358ae030c6d34e2b10a4a4d3e6d3
Author: Geert Janssens <geert at kobaltwit.be>

    Travis fixes
    
    - Remove trailing semicolons. They're not needed in shell scripts
    - Don't create default XDG_DATA_HOME (<HOME>/.local/share) the code
      should work equally well if that directory doesn't exist and so
      not creating it tests another part of the code

commit a8cccc00f31a3b657cd540843dbf590f684da2d7

    Minor tweaks to the userdata_dir logic
    
    - have gnc_validate_directory throw as well in case of a missing directory
      that it shouldn't create. This allows to remove 3 other throws
    - slightly adjust the error message in case of missing directory
    - never migrate when the final directory is a temporary (sub)directory
