Warnings in the Structure Check window doesn't display for molecules with R-Groups

[ZhannaNovikova]

Steps to Reproduce

1. Execute the /v2/indigo/check with the following parameters:
   struct:
   Radical.zip
   options: {
   aromatize-skip-superatoms: true
   gross-formula-add-isotopes: true
   gross-formula-add-rsites: true
   ignore-stereochemistry-errors: true
   mass-skip-error-on-pseudoatoms: false
   smart-layout: true
   },

2. Check the warning

3. Execute the /v2/indigo/check with the following parameters:
   struct:
   Pseudoatom.zip
   options: {
   aromatize-skip-superatoms: true
   gross-formula-add-isotopes: true
   gross-formula-add-rsites: true
   ignore-stereochemistry-errors: true
   mass-skip-error-on-pseudoatoms: false
   smart-layout: true
   },

4. Check the warning

5. Execute the /v2/indigo/check with the following parameters:
   struct:
   Stereochemistry.zip

options: {
aromatize-skip-superatoms: true
gross-formula-add-isotopes: true
gross-formula-add-rsites: true
ignore-stereochemistry-errors: true
mass-skip-error-on-pseudoatoms: false
smart-layout: true
},
6. Check the warning

7. Execute the /v2/indigo/check with the following parameters:
   struct:
   3D Structure.zip
   options: {
   aromatize-skip-superatoms: true
   gross-formula-add-isotopes: true
   gross-formula-add-rsites: true
   ignore-stereochemistry-errors: true
   mass-skip-error-on-pseudoatoms: false
   smart-layout: true
   },

8. Check the warning

9. Execute the /v2/indigo/check with the following parameters:
   struct:
   Chirality.zip

options: {
aromatize-skip-superatoms: true
gross-formula-add-isotopes: true
gross-formula-add-rsites: true
ignore-stereochemistry-errors: true
mass-skip-error-on-pseudoatoms: false
smart-layout: true
},
10. Check the warning

9. Execute the /v2/indigo/check with the following parameters:
   struct:
   Overlapping Atoms.zip

options: {
romatize-skip-superatoms: true
gross-formula-add-isotopes: true
gross-formula-add-rsites: true
ignore-stereochemistry-errors: true
mass-skip-error-on-pseudoatoms: false
smart-layout: true
},
10. Check the warning

Expected behavior:
All types of warnings to be checked are sent in request
Errors are shown as gotten from indigo

Actual behavior:
The Structure Check window doesn't display the warnings according to a list of values are added to the R-Groups
