Improve Name Extraction in Banking Matcher Plugin

[MarcMichalsky]

This commit improves the name extraction for the db mode.

• if there is more than one valid name bit, the last bit will always be the last name
• name bits following the first bit recognised as a last name will not become first names again

Comparison of the results

/**
 * Dummy function

private function isDBFirstName($name_bit) {
  $fistnames = ['John', 'Jane', 'Alice', 'Bob', 'Arthur'];
  return in_array($name_bit, $fistnames);
}

I'm pretty sure @bjendres would like this to depend on a configuration option for the matcher plugin with a default fallback to the current behavior in case someone relies on it.

Well, we could of course just add another mode.

I don't think that's necessary, since @MarcMichalsky introduced a new name_mode called db2.

Yep, after I raised that concern … well, actually still your concern I guess ;-)

@MarcMichalsky thanks, that was quick!

[MarcMichalsky]

Yes, I did that because of @jensschuppe's comment.

Sometimes I lack the perspective of a service provider who serves many customers. I usually only look at problems like this from our perspective. 🙈

As soon as I have time, I'll be happy to write a test for this.

We'll wait for that, then. But if it becomes clear you won't be able to in the near future, give us a shout.

[MarcMichalsky]

Added more logic to cover the common case of <lastname>, <firstname> pattern.

[jensschuppe]

Merged, thanks!

Let's add docs for those CiviBanking plugins, I created #114 as a follow-up.
