export RF filters test unreliable

[Ed McDonagh]

Order of export of exposures to protocol pages on RF xlsx export depends on the similar exposures sorting routine, and therefore isn’t in date or pk order. For some reason this can vary in outcome, and therefore a test that expects a particular exposure on a particular line won’t be reliable.
