Not correct length of head arrow after loading from RDF or layout action

[ivanmaslow]

Steps to Reproduce

1. Add a reaction with Multi-Tailed Arrow from RDF file or add it to Canvas by Tool and click on Layout action:
   head-arrow-size-issue.zip
2. Click on save as, select ket and count the size of head arrow

Actual behavior

• Size of head arrow is about 10.1 (x of head - x of spine):
  

Expected behavior

• Size of head arrow is 6.5 as mentioned in task - Update layout for pathway reaction on canvas #2309
• Loading from RDF file should scale all the structures to the same bond length ( DEFAULT =1.6A)
  For each molecule calculate average bond length AVG - and scale each molecule by AVG/DEFAULT
  If AVG < EPS (0.01) then call layout for a molecule

Environment details

• Detected on CI-CD environment with 2309-update-layout build
