EntityTest::label() is broken and not needed

Updated: Comment #2

Problem/Motivation

EntityTest::label() overrides Entity::label() in case $info->getKey('laebl') == 'name' is TRUE. This is apparently a typo and thus will never be TRUE (unless an entity type would incorrectly specify a laebl entity key). Since tests pass although the code in this condition will never be reached, they should also pass without the code.

Proposed resolution

Remove EntityTest::label()

Remaining tasks

Review patch.

User interface changes

None.

API changes

None.
