When running the tests with options set, such as `-update` for updating
"golden" files, this test would pick up test arguments because no arguments
were set to invoke the command;
go test . -update
Error: unknown shorthand flag: 'u' in -update
Usage:
events [OPTIONS] [flags]
Flags:
-f, --filter filter Filter output based on conditions provided
--format string Format output using a custom template:
'json': Print in JSON format
'TEMPLATE': Print output using the given Go template.
Refer to https://docs.docker.com/go/formatting/ for more information about formatting output with templates
-h, --help help for events
--since string Show all events created since timestamp
--until string Stream events until this timestamp

This patch:
- changes the test to use command-arguments instead of manually setting the
flag options; this also adds test-coverage for parsing actual command arguments.
- discards stdout/stderr of the command to prevent noise in test output
