Subject: [PATCH] Fix naddr routing for replaceable events (kind 10000-19999)

Replaceable events have no d-tag, so useAddrEvent must omit the #d
filter for kinds in the 10000-19999 range. Without this, querying
for a kind 10008 profile badges event via naddr would include
'#d': [''] in the filter, which fails to match events without a d-tag.
