Need implicit H cleanup after rdMolEnumerator.Enumerate()

Describe the bug
When enumerating this query:

qry = Chem.MolFromMolBlock('''

''')

which corresponds to this molecule:

The SMARTS generated indicate that the N atom which doesn't get the attachment point ends up an implicit H:

for m in rdMolEnumerator.Enumerate(qry):
    print(Chem.MolToSmarts(m))

produces:

[#6]1:[#6]:[#6]:[#7]:[#6]2:[#6]:1:[#7]:[#6]:[#7H]:2-[#6]
[#6]1:[#6]:[#6]:[#7]:[#6]2:[#6]:1:[#7](:[#6]:[#7H]:2)-[#6]

Expected behavior
The SMARTS for those should be:

[#6]1:[#6]:[#6]:[#7]:[#6]2:[#6]:1:[#7]:[#6]:[#7]:2-[#6]
[#6]1:[#6]:[#6]:[#7]:[#6]2:[#6]:1:[#7](:[#6]:[#7]:2)-[#6]
