e2e tests run on every commit

[mindctrl]

The Circle config implies that we want e2e tests to run only when tags are created.

atomic-blocks/.circleci/config.yml

Lines 258 to 261 in 588a00b

	- e2e-tests:
	filters:
	tags:
	only: /.*/

But they run on every commit, because the config is missing the branch ignore part like we use elsewhere.

atomic-blocks/.circleci/config.yml

Lines 289 to 290 in 588a00b

	branches:
	ignore: /.*/

Here's a workflow that run when a commit was pushed, and you can see the e2e tests ran.

We just need to add the branch ignore logic to the e2e-tests workflow.
