There are e2e tests that are causing breaks in slower environments like CI:

• test_connection_crossing
• test_non_fastforward_identity_doc

e2e: Fix race condition in test_non_fastforward_identity_doc

e2e: Add limit to test_connection_crossing loop

Changes:

• Rebase
• Dropped the commit attempting to fix the HEAD issue – a solution was merged already
• Squashed the iteration commit into the loop commit – updated the commit body to describe the change
