Fix unit tests

[swissspidy]

Trying to fix tests after wp-cli/wp-cli-tests#206

I realized we were not actually running tests against PHP 5.3, only 5.6+, so I figured we can just bump the requirement while at it.

To-do:

• Figure out why tests are failing on CI, the autoloader doesn't seem to be working anymore... 🤔 Any help appreciated!

@swissspidy It seems like on local, tests autoloading has no effect. Tests are running on local even when I disable this line

php-cli-tools/tests/bootstrap.php

Line 22 in 6507ba2

spl_autoload_register( 'cli_autoload' );

Can I send some tests commits to this PR?

[swissspidy]

Yes I noticed that too, but no idea why.

And the error message on CI don't seem to make sense either

PHP Warning:  Uncaught require(/home/runner/work/php-cli-tools/php-cli-tools/lib/cli/Table/Ascii.php): failed to open stream: No such file or directory

/home/runner/work/php-cli-tools/php-cli-tools/tests/bootstrap.php:19

/lib/cli/Table/Ascii.php does exist

Error message have Table in the path while the directory name is table.

That was it! Thanks @thelovekesh!

Still a mystery to me, why it was not reproducible on my local 🤔. I guess it has something to do with tests custom autoloader.

Case insensitive filesystem I suppose
