2.3RC4 does not clear Guis based on TestBean

[asfimport]

Sebb (Bug 43332):
Create a JDBC sampler, enter some data
Create a second JDBC sampler - the data is copied from the old sampler.

This is new to 2.3RC4 - it worked in 2.2 and 2.3RC3.

However, this was probably because of #1992 which was fixed in 2.3RC3.

It looks like the problem is that the clearGui() method is not implemented for
TestBeanGUI.

I'm working on it - this is just to record the problem so it is not lost.

Severity: normal
OS: other

See also Bug 43292 which relates to the Java Request Gui (though that has
always been a bug)
