theme service should reset protocols handler at de-activation time
------------------------------------------------------------------
Key: NXP-6213
URL: https://jira.nuxeo.org/browse/NXP-6213
Project: Nuxeo Enterprise Platform
Issue Type: Bug
Components: Themes
Affects Versions: 5.4, 5.3.1
Reporter: Stéphane Lacoin
Priority: Major
Fix For: 5.4.1
At initialization time, theme is installing an URL stream URL handler factory
for handling with the 'nxtheme' protocol. As there is no de-installing logic in
place, next activation of the plugin will use an incorrect instance of the
factory (de-referenced class).

Impacts are
* remove the use of the URLStreamHandlerFactoryInstaller (Manager) (This way of
initializing was introduced because of surefire bug (SUREFIRE-104). We can
safely remove this way of initializing because the bug is solved in the
surefire version we're using now (>=2.4))
* introduce the resetProtocols method that will remove the
"org.nuxeo.theme.protocol" and reset the handler cache (Manager)
* initialize and reset protocol handlers during service activation
(ThemeService)
