Thiagodeev/fix-flaky-tests (#799)

* fix: TestBuildAndEstimateDeployAccountTxn test balance error

* fix: TestGetStorageProof test 'too far in the past' error

Sometimes, when the second call was being made, it was no longer the latest block, and since this method only works on the latest, an error was being returned

* fix: TestSubscribeEvents flaky tests

Removed some validations not necessary to test starknet.go logic

* test: increase TestSubscribeNewTransactions timeout time

* test: add missing return and other improvements in TestSubscribeEvents test

* test: refactor timeout handling in TestSubscribeEvents and related tests

* test: rename testEnvStr var to envStr
