Percentage sign in link reference needs to be escaped

The LinkBlock LaTeX  template should escape percentage signs (LaTeX line comment symbols) in the link reference.

Currently, the XWiki text

**[[Link to page with spaces in name>>doc:Page with Spaces in Name]]**

translates to

\textbf{\href{http://localhost:8080/xwiki/bin/view/Test/Page%20with%20Spaces%20in%20Name}{Link to page with spaces in name}}

which turns everything after "Page" into a comment and makes the LaTeX compiler produce the error message:

! File ended while scanning use of \textbf .

Side note: Without the bold format, the produced LaTeX code would not contain the \textbf{} and would compile correctly for reasons I do not understand.
