Remove null elements from LDAP attributes array

[tjmcomp]

fixes #14

[luelista]

Hi @tjmcomp,
thanks for your tracing that bug and opening this merge request (:
I'd change two things:

• I don't like the new gitignore, JetBrains recommends otherwise
• I'd rather create the ldapArray depending on the actual size of the ldapAttributes list.

If you have the time, could you change it? Otherwise, I'll do the change myself when I get around to recompiling the app (need to find the certs...)

Hi.

I'll revert the gitignore changes to keep it as you had it already.

I did think the size - 2 was a bit simple. :) I'll update today.

I have added a fix for #16 to this pr as well, since I need it for my use case. I may just resurrect my play store account and publish a separate build anyway, but it won't be soon so i'll leave this pr for you to merge when you get a chance.

Hi @tjmcomp ,
if you want to take over maintaining this app, feel free - I can add a link to your repo in the README if you want. I'm currently not using the app myself, and don't have the spare time to maintain it for fun, so I won't be able to push a new release soon.
Best,
Mira
