Output DEF creates illegal DEF for instance HALOs

[Colin-Holehouse]

Running the enclose tcl script on a DEF with a component that has a HALO defined, the output DEF has written an illegal syntax for the HALO description. From the transcript you can see that parentheses have been used
halo_test.tar.gz
when writing out the DEF that should not be present.

Transcript as follows:
