Fixed issues with invalid cell layout

[paweldudek]

This small change fixes an issue with multi value section having invalid layout on iPad when a new row is added.

Form table view cells use auto layout for laying out subviews, however the call after cell configuration used old

setNeedsLayout

call to inform the cell that it should update its layout. This was changed to

setNeedsUpdateConstraints

Example image how it looked before the fix:

hey @paweldudek ,
Thanks for the contribution. Maybe we should keep setNeedsLayout to support UItableViewCells that don't use autolayout.

I mean,

[cell setNeedsUpdateConstraints];
[cell setNeedsLayout];

instead of

[cell setNeedsUpdateConstraints];

Could you please make another pull request adding this line? Also make sure it works on your ipad app.

I will add tests and an ipad example soon.

I'm a huge fan of 'don't write code that's not yet needed' (and removing the setNeedsLayout call didn't affect other existing cells), but if you insist ;)

I've added the

setNeedsLayout

call. And yes, it does work on iPad.
