Perform stats ping immediately on startup

[emerick]

Description

We ping the stats server once an hour while the browser is running, but we must also ping the server immediately upon startup as well. In addition, this startup ping should occur 3 seconds after startup to match the timing of our referral initialization ping.

Steps to Reproduce

1. Start Brave.
2. Start a network analyzer, such as Fiddler on Windows. (or use --enable-logging --v=1)
3. Wait for more than 2 minutes (this was the original expected time of the startup ping).

Actual result:

No ping is sent to https://laptop-updates.brave.com/1/usage/brave-core until a full hour elapses.

Expected result:

A ping such as the following is sent to the stats server:

GET https://laptop-updates.brave.com/1/usage/brave-core?platform=winx64-bc&channel=release&version=0.59.1&daily=false&weekly=false&monthly=false&first=false&woi=2018-11-19&ref=none HTTP/1.1

Accept-Encoding: gzip, deflate, br

Reproduces how often:

Every time.

@emerick when running Brave using --enable-logging --v=1, noticed the following stats ping:

[17428:775:1128/210809.765356:VERBOSE1:brave_stats_updater.cc(145)] Brave stats ping, url: https://laptop-updates.brave.com/1/usage/brave-core?platform=osx-bc&channel=beta&version=0.57.8&daily=false&weekly=false&monthly=false&first=false&woi=2018-11-26&ref=none

Wasn't using a referral installation hence ref=none, but is this the ping that we're looking for in the logs?

[emerick]

Yes, exactly!
