Linker: Avoid passing false to Title::newFromText

This is needed because the call to substr() returns false when the string
is only 1 character long, which occurs when parsing degenerate links like
[[:]] and [[::|foo]].

The seemingly unnecessary test for $match[1] !== '' is for forwards
compatibility with PHP 7.

Bug: T121706
Change-Id: Icc19ee990d01958d64b938d298e9a7e1df7181b5
