chore: lint tests

[faddat]

Description

This PR lints the tests for evmos. The most common/productive finding from linting the tests to ibc-go, Gaia, and the cosmos-sdk has been that we can improve test quality and formatting by changing to tests:true in .golangci.yml. The most common improvement is checking for errors more frequently.

@faddat Looks good, but can you address the comments left by @GAtom22 ? Otherwise it might be wise to move this PR to draft for the time being.
