Make bind/schema acceptance test run locally (#2463)

## Changes
<!-- Brief summary of your changes that is easy to understand -->
1. Change the cloud acceptance test for `bind/schema` to run locally
2. Add debug lines to the mock server
3. Change `fake_workspace` to create directories for imported files

## Why
<!-- Why are these changes needed? Provide the context that the reviewer
might be missing.
For example, were there any decisions behind the change that are not
reflected in the code itself? -->
1. Local version of the test run can indicate breaking changes faster
than the cloud version and it can be run locally without any predefined
environment variables

## Tests
<!-- How have you tested the changes? -->
1. Ran both acloud and local versions of test, both succeeded

<!-- If your PR needs to be included in the release notes for next
release,
add a separate entry in NEXT_CHANGELOG.md as part of your PR. -->
