sanitize_term_field missing default $context value

[dilipbheda]

As per the inline documentation of the sanitize_term_field() function, a default $context value should be passed in the function arguments.

Hello and thank you for the ticket.
I may be wrong but to be honest, given the default condition passes through a simple else statement, I cannot see much value to pass the default value. It is not used anywhere in the function.

@audrasjb You're right, but I noticed that the documentation mentions a Default value, which implies that if the last parameter is not passed, it should default to the 'display' context.

Or we can remove the default value mentioned in the inline docs.

Defining the default $context = 'display' avoids errors if the function gets called without the $context parameter so it's making sense to me. For that reason it will be possible to also call the function with only the first 4 parameters, if needed. Also it is clearer in regards to the inline documentation.

You make a point @Presskopp. Let's add the default then.
