docs(tutorial/step_4: update test to match new $bindings behaviour

var phoneNameColumn = element.all(by.repeater('phone in phones').column('{{phone.name}}'));
should be
var phoneNameColumn = element.all(by.repeater('phone in phones').column('phone.name'));

Closes #9823
test($route): fix test names
fix($route): fix redirection with optional/eager params

Previously, when (automatically) redirecting from path that fetured a
trailing slash and optional or "eager" parameters, the resulting path
would (incorrectly) contain the special characters (`?`,`*`) along with
the parameter values.
