acc: Fix local inprocess tests when run from IDE (#3056)

## Changes
- Do not load env variables from ~/.databricks/debug-env.json, revert
#2765
- Better check in TestInprocess that test is actually run and not
selected.

## Why
Loading those env vars sets CLOUD_ENV which makes test runner ignore
local tests.

## Tests
Manually. Set selftest/basic Cloud=false and run it via IDE.
