Fix array to string conversion on event search

  "level": 3,

  "version": "20.0.0.7"
}

Values come from:

server/apps/dav/lib/Search/EventsSearchProvider.php

Lines 61 to 64 in 2a054e6

	private static $searchParameters = [
	'ATTENDEE' => ['CN'],
	'ORGANIZER' => ['CN'],
	];

Go in here:

server/apps/dav/lib/Search/EventsSearchProvider.php

Line 113 in 2a054e6

self::$searchParameters,

And end up as a "Str" parameter instead of array:

server/apps/dav/lib/CalDAV/CalDavBackend.php

Lines 1780 to 1786 in 7d06027

	foreach ($searchParameters as $property => $parameter) {
	$parameterAnd = $calendarObjectIdQuery->expr()->andX();
	$parameterAnd->add($calendarObjectIdQuery->expr()->eq('cob.name', $calendarObjectIdQuery->createNamedParameter($property, IQueryBuilder::PARAM_STR)));
	$parameterAnd->add($calendarObjectIdQuery->expr()->eq('cob.parameter', $calendarObjectIdQuery->createNamedParameter($parameter, IQueryBuilder::PARAM_STR)));
	$searchOr->add($parameterAnd);
	}
