Fix e2e tests due to duplicate rows when clearing customizations

[Aljullu]

Changes proposed in this Pull Request:

There are some tests failing in trunk because when we try to revert template customizations from the automated tests, there are two rows which match the Single Product text (Single Product and Single Product Belt). That causes the tests to fail because there are two matches for the locator.

This PR makes the locator more specific, so there is only one match even if two templates contain the same words.

How to test the changes in this Pull Request:

Note: no need to test this for the release.

1. Verify e2e tests pass.
