Update dependencies to make it compatible with Laravel9

[asbiin]

Description

Update pragmarx/ia-collection, pragmarx/ia-str and pragmarx/ia-arr dependencies. Also remove composer.lock and update travis config file.

Motivation and context

Laravel 9.x requires symfony/var-dumper ^6.0 and voku/portable-ascii ^2.0. This is part of some updates on multiple pragmarx packages which aren't compatible with Laravel9 yet, this helps fixing that.

I am not the maintainer of the repo, and it does not seem to care anymore. I don't need this package myself, I'll left the PR as is but I am not working nor waiting on it.
