fix HTML display for mismatching number of frequent items between profiles

[FelipeAdachi]

Description

When reference_profile had a higher number of frequentItems than target_profile, profile_viewer generated broken HTML file, because the logic iterated on target_profile and used index to try to access reference_profile.

Changed to:

• Iterate based on min. number of frequentItems
• frequentItem Strings loaded w/ empty string when trying to access not-existing index
