Angular version has been upgraded to 8.2. In addition, "npm audit fix"
has been run to fix any security issue.

A bug was causing the "Limpiar" button of the people view not to work,
as the event-managing method was calling itself. This bugfix solves this
problem by changing the method called by the event-managing method.

The auto-redeploy mode now ignores node_modules, as it slows excesively
down the execution.

The PeopleResourceTests now include security tests to verify that normal
users can't access people data.

The example done for JavaScript, were people can be managed, has been
migrated to Angular.
