remove lyon finances report page

Fixes #394

[DelazJ]

@rduivenvoorde I wonder if Travis is really active on this repo too. With removing the Lyon report file but not removing its mention in the index toc file, Travis should return a warning. But as you can see, all is green

@rduivenvoorde despite the green light, checking the Travis report shows:

Warning, treated as error:

/home/travis/build/qgis/QGIS-Website/source/site/getinvolved/governance/developer_meetings/index.rst:6: WARNING: toctree contains reference to nonexisting document u'site/getinvolved/governance/developer_meetings/lyon_finances_report'
make: [html] Error 1 (ignored)
Build finished. The HTML pages for 'en' are in output/html/en.
The command "make html" exited with 0.
Done. Your build exited with 0.

@alexbruy could you please fix that (and maybe also revert changes in config file, unless it does change nothing)?

@DelazJ done

Sorry for the delay, @alexbruy
