(GH-1327) AutoUninstaller - split multiple file paths

Say the uninstall string was specified like this:
`C:\Programs\WinDirStat\Uninstall.exe D:\Programs\WinDirStat`

Running uninstall will produce the following message from automatic
uninstaller:

~~~sh
2017-06-06 13:42:13,463 5244 [INFO ] -  Running auto uninstaller...
2017-06-06 13:42:13,463 5244 [DEBUG] -   Sleeping for 2 seconds to

2017-06-06 13:42:15,479 5244 [DEBUG] -  Uninstaller path is

2017-06-06 13:42:15,495 5244 [INFO ] -  Skipping auto uninstaller - The
uninstaller file no longer exists.
"C:\Programs\WinDirStat\Uninstall.exe D:\Programs\WinDirStat"
~~~

Split the paths when multiple `:` are detected.
