Visiting hero through monolith does not works

[IvanSavenko]

Describe the bug
If your hero stands on one end of monolith and another your hero attempts to enter same monolith from other side then nothing would happen

To Reproduce
Steps to reproduce the behavior:

1. Have one hero go through monolith / subterranean gates
2. Move another hero to the same monolith / subterranean gates

• Subterranean gates can be checked on "All for one" map
• Two-way monolith can be checked on "Deluge" map
• One-way monolith can be checked on "Carpe Diem" map

Expected behavior

• If there is allied hero on the other side of the monolith, game should initiate hero exchange, just like on meeting hero directly
• If there is enemy hero on the other side, game should initiate combat
• This mechanics should apply to all(?) teleporters - subterra gates, two-way monolith, probably also to one-way monoliths (TODO: double-check H3)
• TODO: check how H3 handles cases when monolith has multiple possible exits

Actual behavior
Nothing. Monolith visitation sound plays, but nothing happens

Did it work earlier?
May have worked long ago

At least initiating combat worked in the past
