This is to fix the situation when cells merged vertically are ignored in columns auto size calculations.
I also removed $calculateMergeCells param as it wasn't used and I believe the only situation when you
want to calculate the width of merged columns has been covered here (and there's no reason to not calculate it).

Some references to classes were incorrectly assumed to be a reference
to self, whereas they were references to classes in global namespace
outside of this project.

GD is implicitly required for saving images anyway, this exception when
it's not loaded simply gives more information on what to do if the
execution flow reaches a places that depends on a function from GD.
```php
<?php
$array = array(
'str' => 'foo',
'num' => 12345,
'null' => NULL,
);
print intval(isset($array['null'])) . PHP_EOL;
print intval(array_key_exists($array['null'])) . PHP_EOL;
print intval(isset($array['num'])) . PHP_EOL;
print intval(array_key_exists($array['num'])) . PHP_EOL;
print intval(isset($array['str'])) . PHP_EOL;
print intval(array_key_exists($array['str'])) . PHP_EOL;
```
Only for this special case, you need array_key_exists(), else avoid it as it is
painfully slow and hurts your performance.

If a sheet name included an apostrophe and the sheet had print area
defined then the spreadsheet could not be saved because the cell
coordinates were mangled, eg:
'Fiche d''action'!$A$1:$N$19
wrongly became:
'Fiche d'$A$1:$N$19
Tests that run too long without output tends to break Travis builds.
This is typically the case when running code-coverage, so we need to
exclude a few test cases to ensure that the builds are stable.
