Implicit H count is not added to the SMARTS file

[urszula-gawlowska]

Steps to Reproduce

1. Launch "Ketcher"
2. Draw structure on the canvas
3. Double click on any atom
4. Go to "Query specific" section
5. Set Implicit H count to 5
6. Click 'Apply'
7. Click on the "Save as" button
8. Select the "Daylight SMARTS" file format

Expected behavior
Implicit H count should be marked at the SMARTS file as: h5

Actual behavior
SMARTS is created in the incorrect way:

[#6](-[#6])(-[#6])-[#6]

It is noticed that when any other attribute for atom (e.g. Substitution count) is set up together with implicit H count then it is save properly at SMARTS file
