Fix DataRegion Locators for "Experiment Runs" webpart

[labkey-tchad]

Rationale

"Experiment Runs" data region no longer has a predictable name ("Runs"). Tests need to be updated.

org.openqa.selenium.NoSuchElementException: Expected condition failed: waiting for css=form[data-region-form="Runs"]
(tried for 30 seconds with 100 milliseconds interval)
  [...] app//org.labkey.test.components.WebDriverComponent$WebDriverComponentFinder.waitFor(WebDriverComponent.java:86)
  at app//org.labkey.test.tests.DataClassFolderExportImportTest.testExportImportSimpleDataClass(DataClassFolderExportImportTest.java:137)

Also fixing and cleaning up some nearby test code.
