the contract methods call function mutates its options argument

[karmaniverous]

Is there an existing issue for this?

• [X] I have searched the existing issues

Current Behavior

A simple options argument passed to the call function acquires new keys.

{ from: '0xD28D1f59...' }

becomes

{
  from: '0xd28d1f59...',
  data: '0x5e615a6b',
  gasPrice: undefined,
  gas: undefined,
  to: '0xb97da33a...'
}

after the call.

Expected Behavior

This function shouldn't mutate its configuration arguments. This cause problems when you want to reuse them elsewhere.
