mdstcl's do/method on python devices closes the tree parenting the device

[zack-vii]

assuming \TESTTREE::TOP:DEVICE_PATH is a device that has a method 'method(self,*arg)'
The new doMethod seems to still close all trees on return.
mdstcl is segfaulting on attempt to reopen tree.

TCL> set tree testtree
TCL> show db
000  testtree             shot: -1  [\TESTTREE::TOP]

TCL> do/method device_path method
TCL> show db

TCL> set tree testtree
Segmentation fault

The issue presumed despite downgrading due to residual python packages of the most recent version.
The trees do not close unless the method opens another tree after reverting #281, #267, and #261 (TreeRef related)

[zack-vii]

The closing of the trees occurs between #281 and #267, in version 7.0.202 the method segfaults immediately

TCL> set tree testtree
TCL> do/method device_path method
Segmentation fault

[zack-vii]

never mind. in fact #281 fixed the problem but I had a hard time testing it correctly. 202 works now

Should be fixed by pull request 281 merged yesterday.
