This reverts commit 42ff50300cff7558fd03cdebb757eca8caf85199.

This reverts commit c061f2e2, reversing
changes made to 6e007b1e.

These were causing the tests to fail and should be fixed by the update to FindByXpath function.

Use the same implementation as onSetProjectThumbnailer which does the same thing for getting a thumbnail externally.

Account for the addition of locale prop expected in mapStateToProps.
Note: if/when the telemetry code gets moved into its own hoc, the prop should get removed, and the test should get updated as well.
