browser: contributor local test undefined OR null originalId

Some data is using originalId as `null` to represent local contributors,
while others are using originalId as `undefined`. Account for both
possibilities when determining whether a contributor is local or
StackOverflow.

Closes #275
fix(e2e): don't assume accountInfoLabel is present
fix(e2e) correct spelling of "loginIfNecessary"
fix(e2e): handle "name" property of Page object constructor correctly

Page object constructors were using the "name" property to indicate the
"code-ish" name for them when they were added to World.

The "name" property of a constructor is off limits and so instead we
had the constructor's actual name being used.

Use "pageName" property to define pages' names in order to avoid this
conflict.

fix(e2e): rename scenario

Rename a scenario that no longer described what it was testing.
e2e: getElementIfPresent function

Issues with protractor isPresent/isPresent element make it safer to
do this ourselves. Make a function that returns a promise of
an element or null, depending on if the locator points to a present
element.
e2e: work around cucumber next callback -> notifyOk

Cucumber's next function isn't promisified and thus considers a
truthy parameter to be an indicator of failure.

This is not an issue when we are dealing with chai-as-promised
expectations because they have .and.notify support.

Create a sugar function to be used when we don't have an expectation so
that any value which happens to be resolved in by a steps function
does not trick Cucumber into thinking something went wrong.
