STORM-488 FIXED Place profile was opened instead of Object profile if used clicked an object SLURL in the plain text nearby chat log.

The reason is the same as in STORM-390: a bug in LLTextBase which leads to ignoring link href specified for a link segment if
the segment contains an URL (and the <nolink>...</nolink> clause is treated as such).

The workaround is to explicitly disallow parsing URLs in a link segment by setting its "is_link" parameter to "true".
