Tests: skip linkRowsAfterLazyEdit on a build without --run

linkRowsAfterLazyEdit() (#1523) edits a project through --run, which a
QElectroTech built without Qt Qml does not have. The Linux CI builds it
that way, so the test has failed there since #1523 merged, on master
(e46bb97c5) and on every pull request after it: "MOVED true" is never
printed. It now skips, as the five other --run tests of
tst_resaveunchanged do.
