BUG: missing int cast

Yes

I have checked that there are no already open issues or recently closed issues about this bug
Yes

Describe the bug
Missing int cast to compare uid with a potential string: https://github.com/FluidTYPO3/vhs/blob/development/Classes/ViewHelpers/Condition/Iterator/ContainsViewHelper.php#L132

To Reproduce
Steps to reproduce the behavior:

have this in a news template (needle is a string here!):

<v:condition.iterator.contains needle="{overwriteDemand.categories}" haystack="{newsItem.categories}">
	<f:then>yes</f:then>
	<f:else>no</f:else>
</v:condition.iterator.contains>

Expected behavior
output yes but always no.

cast to needle to int as uid is always an int but needle can be a string as well (coming from fluid template)

Fix this quickly by casting: {overwriteDemand.categories as int}.

Side note: this condition would probably break or not work correctly; {overwriteDemand.categories} does not look like it would always contain a single value and needle must be a single value. If it works then that is by coincidence and you should extract/convert as needed to ensure it is always a single value, or use a different condition based on iterator.intersect to compare if iterators A and B have any elements in common.
