[TYPO3-core] RFC #15417: Bug: [Caching framework] DbBackend has() returns false for entries with unlimited lifetime

[Christian Kuhn]

This is an SVN patch request

Type: bugfix

Branches: trunk, 4.4, 4.3

BT: http://bugs.typo3.org/view.php?id=15417

Problem:
DbBackend has() returns FALSE for entries with unlimited (0) lifetime. 
The constructed where clause misses this case.

Solution:
Add proper case to where clause.

How to test:
Apply _test and watch it fail. Apply patch and see that it works.

Notes:
4.3 needs a slightly different test, while code change in dbbackend is 
identical.
Thanks to Chris Zepernick for pointing that out!

Regards
Christian
