getWrap behaviour change in v4

In this change https://github.com/diegomura/react-pdf/commit/481b536f4ad145fb227829399b85a35838a506f8#diff-787134450138de88787ea4fed051cb798a2e3a5816955746ab7730617ae6d6e3R11

getWrap inside getWrap.ts was slightly altered resulting in different behaviour.

Now when passing an undefined wrap prop it is treated as `wrap=false`
