Buying Pack with insufficient FUSD silently fails

[bebner]

Describe the bug
The purchase of a Pack with insufficient FUSD funds silently fails.

To Reproduce
Steps to reproduce the behavior:

1. Enable FUSD Wallet (if not enabled yet) by clicking on "Enable FUSD" in the upper left corner of the page.
2. Set up a collection (if not set up yet) by navigating to "Collection" and then click on "Enable Collection"
3. Navigate to Packs page and click on any pack
4. Click on the FUSD price (needs to be higher than your FUSD balance) to purchase the pack and confirm the transaction
5. See that nothing happens

Expected behavior
The expected behaviour would be an error message or alert that the FUSD balance is not sufficient and therefore the purchase is aborted.
