Prevent hie crash if apply-refact crashes

[Hogeyama]

Fixes #451

Note: We need to catch SomeException because applyRefactorings throw an error by error.

[fendor]

We never catch SomeException, because of async exceptions.
If the error has been issued by error you can catch ErrorCall

[fendor]

You can use catches :: IO a -> [Handler a] -> IO a and catch both IOException and ErrorCall

EDIT: catches looks like it has a wrong type, however, I hope the idea is clear.
Maybe catchJust or tryJust fit better?

[Hogeyama]

Oh, I missed the edit. I'll rewrite it by using tryJust

[fendor]

If it works, I wouldn't change it. I thought, it may not do what we expected.

However, do you have some kind of tests to validate that this really fixes the problem? Would be great to have a test or two for regression testing!

[fendor]

Looks great now!

[Hogeyama]

Thank you!
