* add a bunch of tests, add DONTCOVER text tag
- Also fix flaky test (closes: #3559). Don't test values
returned by queries since there's no way to query a
specific height via REST.
* GetTempDir -> NewTestCaseDir
Throughout the codebase the misspelling 'depositer' of the English word
'depositor' has been used. This commit applies a global search and
replace to correct the misspelling.
* Move query and tx commands to modules
* Move GetAccountDecoder to prevent import cycle and replace calls to it with one call in WithAccountDecoder
* Add moduleClients interface and implement in all applicable modules
* Use module clients in cli initialization
