Fix rerun button not disabled for ES-MDA

[jonathan-eq]

Issue
Resolves #9811

Approach
This commit fixes the issue where the rerun button was enabled for ES-MDA and ensemble smoother. The issue was due to us setting support_restart before calling the super class' constructor which overwrote it to False.

(Screenshot of new behavior in GUI if applicable)

• PR title captures the intent of the changes, and is fitting for release notes.
• Added appropriate release note label
• Commit history is consistent and clean, in line with the contribution guidelines.
• Make sure unit tests pass locally after every commit (git rebase -i main --exec 'pytest tests/ert/unit_tests -n auto --hypothesis-profile=fast -m "not integration_test"')

When applicable

• When there are user facing changes: Updated documentation
• New behavior or changes to existing untested code: Ensured that unit tests are added (See Ground Rules).
• Large PR: Prepare changes in small commits for more convenient review
• Bug fix: Add regression test for the bug

Could this be backported to the 12.1 branch as well (if the bug is present there)? 🙂
