Fix: skip Balancer script if global one is already created

Hi, this is a great library, thanks for developing it :)

The problem I stumbled upon (and am fixing in this PR) is as follows.

There are two ways to use this library:

• You use Balancer without a Provider. In this case, each Balancer has its own script that calculates the layout and does other things.
• You use a Balancer with a Provider. In this case, they all have one common script that calculates the layout.

Now imagine you have a strict CSP and you need to pass a nonce. You pass the nonce to the Provider and do not pass it to Balancers.

This lib creates an empty script tag for each Balancer in case of global script injection. Since you don't pass the nonce to each Balancer, the CSP doesn't work (as there still is a script for each Balancer).

I fixed this by just not returning any script tag in case of global script injection. Seems that this PR is associated with https://github.com/shuding/react-wrap-balancer/issues/78, but I'm not sure
