Add missing dependency on TemplateURLService from PrefMetricsService

Add missing dependency on TemplateURLService from PrefMetricsService

There is an indirect dependency from PrefMetricsService on TemplateURLService
that cause an incorrect ordering of the factories instantiation when using a
TestingProfile, as can be seen in the following callstack:

TemplateURLServiceFactory::GetForProfile(Profile*)
chrome::(anonymous namespace)::GetDefaultSearchProviderTemplateURL(Profile*)
chrome::(anonymous namespace)::NewTabURLDetails::ForProfile(Profile*)1
chrome::HandleNewTabURLRewrite(GURL*, content::BrowserContext*)
content::BrowserURLHandlerImpl::RewriteURLIfNecessary(GURL*, content::BrowserContext*, bool*)
(anonymous namespace)::SampleNewTabPageURL(Profile*)
PrefMetricsService::RecordLaunchPrefs()
PrefMetricsService::PrefMetricsService(Profile*)
PrefMetricsService::Factory::BuildServiceInstanceFor(content::BrowserContext*)

Add an explicit dependency to fix the ordering.

Please have a look.

This is causing the failure of
StackedPanelBrowserTest.AddNewPanelFromDifferentProfile in one of my CL that is
using the already declared dependency of TemplateURLService on HistoryService.
