A failed example may end up in an abort if a non-captured tag is used (+paste)

**Is your feature request related to a problem? Please describe.**
When a example fails, skip the rest which it is ok. To support basic tear-down functionality the ``-skip`` prevents an example to be skipped.
The unhappy situation is when an example fails, the next example which outputs should be captured is skipped and then the next example is executed (``-skip``) and tries to use the captured text (``+paste``)

This last one does not exist and the whole execution aborts. The abort was thought as a fast catch-up if the user misspells a tag name but now, the tag is not available not because a user typo but because some example failed.
