fix: wait for tx committed before read its data

[chaoticlonghair]

Description

Some tests have read data from contracts, before the transaction which changes the data is committed.

These bugs are only happened after axonweb3/axon#1526 and only in CI because:

• After fix: check mempool when call eth_getTransactionByHash axon#1526, the eth_getTransactionByHash has data when transactions just in mempool, so the call of functions will return earlier.
• The CI environment is low performance, but our local development is good enough.

Tests

Before this PR:

• Failed test #7
• Failed test #8
• Failed test #10

After this PR:

• The above tests are fixed.
  p.s. That CI check still has failed tests, they will be fixed in other PRs later; I haven't figured out them now.
