'type error during .tst.restore when mocking data namespace within the global namespace

[danielkrizian]

Mocking the data namespace (without the leading dot):

$ cat test.q
.tst.desc["Mocking"]{
 should["support data namespace within the global namespace"]{
  `myns.a mock `foo;
  `myns.b mock `bar;
  };
 };

throws a 'type error (namespaces with the leading dot work fine).
Exploring the environment reveals the root cause:

$ testq --fail-hard test.q
'type
  [9]  /home/dk/conda/q/lib/qspec-1.3.3/mock.q:28: .tst.restore:
 / Drop each fully qualified symbol from its respective namespace
 if[count removeList;(.[;();_;]') . flip ((` sv -1 _;last) @\: ` vs) each removeList];
                                  ^
 `.tst.removeList set ();
q.tst))`myns.a`myns.b in removeList
11b
q.tst))-3!myns
"()"
q.tst))get `..myns
 | ::
a| `foo
b| `bar
q.tst))flip ((` sv -1 _;last) @\: ` vs) each `myns.a`myns.b
myns myns
a    b   
q.tst)).[`myns;();_;`a]               / failure
'type
  [11] .[`myns;();_;`a]
       ^
q.tst)).[`..myns;();_;`a]             / success
`..myns
q.tst))get `..myns
 | ::
b| `bar

Data namespaces (the ones without the leading dot) within removeList are malformed. Instead of `ns.a`ns.b , their fully-qualified name should be `..ns.a`..ns.b.
