coala shouldn't store previous input values in case of failed execution

[srisankethu]

Noticed case:

I tried opening affected files in an editor.I gave an invalid editor name and the execution failed.But when I tried to open the editor again, i get an error because coala takes in the 'number of action' and applies it to check the editor name.

so for clarification:
After a failed OpenEditorAction, the editor-name is saved for the next try. So i if the user retries now, he isn't asked for the editor again and coala tries to reopen the invalid editor again, which immediately leads to failing again.

Yes!...Can you assign this to me?
