Require icalendar-searcher>=1.0.5

v1.0.5 fixes two bugs needed for our tests:
- undef filter for CATEGORIES was broken with icalendar>=6.x
- undef filter for DTEND was broken for recurring all-day events

Versions 1.0.3 and earlier (the latest on PyPI before this) do not have
these fixes, causing testSearchEvent and test_search.py failures in CI.
