Avoid joining highway=* to landuse=*

[mkoniecz]

What steps will reproduce the problem?

1. Start making highway=* way
2. Attempt to join it to existing highway=* located near landuse=* boundary

What is the expected result?

Crossing of highway=* ways is created - and landuse is not affected (in other words, if one currently extends highway=* and new node would become joined to highway=* way filter out landuse=* ways)

What happens instead?

Crossing of highway=* ways and landuse=* way is created

Please provide any additional information below. Attach a screenshot if possible.
