t6302: use `main` as initial branch name

In 66713e84e71 (tests: prepare aligned mentions of the default branch
name, 2020-10-23), we started adjusting this test script for the default
initial branch name changing to `main`.

However, there is no need to wait for that: let's adjust the test script
to stop relying on a specific initial branch name by setting it
explicitly. This allows us to drop the `PREPARE_FOR_MAIN_BRANCH` prereq
from six test cases.
