Tap runner hides failures

[richtja]

Describe the bug
If one of the tests in tap output is skipped before some failure, avocado will mark the whole output as skip instead of fail and users are not notified about the failure.

Steps to reproduce
TAP output generated by tap test stored in example.tap:

TAP version 13

# MUST be treated as a SKIP test
ok 1 - must be skipped test # SKIP

not ok 2 - actual failure
ok 3 - passed test

bash script for reading this file as test.sh:

#!/bin/bash - 

cat example.tap

JSON for running the tap test as test.json:

[
    {"kind": "tap", "uri": "./test.sh"}
]

Avocado command:

$ avocado run test.json
