Resolves #344.
This PR fixes the reentrant signature reutilization bug by checking that the caller of the Account's
__execute__method is the zero address. Further, this PR proposes to include a mock contract with a malicious function (created by @Solpatium) along with a reentrant call test. Finally, this PR also updates the Account tests to follow the memoization pattern—ensuring current and subsequent Account tests each run from a clean state.
