Format transaction.type to hex. Add empty accessList is tx.type === '0x1'

[spacesailor24]

• transaction.type is now formatted to a hex string before being sent to provider
• When sending a transaction, if transaction.type === '0x1' && transaction.accessList === 'undefined', then transaction.accessList is set to []

Added test cases for Steps to Reproduce examples from here. With these changes everything is formatted as expected, however, we do not throw an error for tx.type exceededing bounds of 0x0 to 0x7f

closes #4597
