[9.x] Default address methods

[jasonmccreary]

Upon using these two methods for the first time recently, my expectation was they would automatically set the column name for me given their specific method names.

I addressed this tiny paper-cut by defaulting the column name inline with Laravel's naming convention (snake case) for both the ipAddress and macAddress methods.

Before

$table->ipAddress('ip_address');
$table->macAddress('mac_address');

After equivalent

$table->ipAddress();
$table->macAddress();

Note: I considered this a breaking change since it updates the method signatures. However, this could be defaulted in another way to merge into Laravel 8.x if desired.

The failure seems unrelated. However, let me know if this somehow affected those tests.

Yep, we're aware master is failing, due to pending upstream (testbench) changes. Should be sort out soon. :)

Hmmm, I don't think I like these defaults.

@GrahamCampbell I felt there were sensible/predictable given Laravel's naming convention and the current method names. I'm open to whatever. These were really just for convenience. One can always pass the argument.
