fix: issue where pasing no params would fail the walletconnect connection

[tomiir]

Description

• Adds an extra check on WC connector to validate that params are being passed in before trying to access it.
• If params were undefined, this would fail the connection call.

Example:
As a Stacks developer I would like to use my WC wallet without needing to specify network parameters explicitly
