[crac] RFR: Ignore errors parsing classpath [v2]

[Radim Vansa]

> This test is relevant mostly on Windows - trying to use URI in the form of `file:/C:/path/to/...` as classpath element. On Linux, this is parsed as two items as `File.pathSeparator` is `:`. However on Windows the second colon triggers an exception.
