CB-10640: Windows logging is broken
**Issue**
In the current system, the logs which are collected in the events must be
listed in the CI logs is broken. For example, if there is a syntax error in one
of the plugins, mobilespec(during testing) will crash the app. This information
is available in event logs. This must be collected in the '[Gathering
logs](https://ci.apache.org/builders/cordova-windows-store8.1/builds/1660/steps/gathering-logs/logs/stdio)'
step and be available in CI logs. But, that is not happening and must be
fixed.
**Root Cause**
The issue is traced to 2 cause.
1. **Query**
The query format that was used to retrieve the event logs is incorrect. For
example, even when the 'View Events Logs' tool reports the error, if you run
the exact command in command line, it just returns empty results. This query
format must be fixed.
2. **spawn**
The _wevtutil_ command is invoked through spawn (for collecting the event
logs). This same approach is used in the same program at 4 different places
(for various reasons). In all other scenarios, the output is correct, But,
while collecting the event logs, the output is empty. This must be fixed.
**Fix**
For Issue 1, the query format has been modified to use _timediff_
parameter. This is the approach that is used by the 'View Events Logs' tool.
The resulting query is executed on both command line and through the script and
confirmed that it is working fine.
For Issue 2, I suspect that the root cause of the issue might be related to
sending the parameters with '/'. But this theory could not be confirmed and
modifying this did not work. Instead, the execSync approach did work fine. The
same has been used.
**Testing**
Two scenarios has been tested.
1. **log using the medic.js**
This approach gets the logs for the last 27 minutes. It produces correct
results as expected.
2. **Execute log directly without dump option**
In this scenario, it has to continuously display the logs repeatedly with 1
second interval (until manually interrupted).It produces correct results as
expected.
