Fix tests: Put space back after comma between ORM annotation properties

[baspeeters]

Problem

1. Tests for GenerateTypeCommand were failing
2. Cause was a space missing after the comma between @ORM\Column parameters:

Actual:

* @ORM\Column(type="text",nullable=true)

Expected:

* @ORM\Column(type="text", nullable=true)

Research

1. I had wrongly only adapted the test to this (never a good idea) in Remove an expected annotation space in test #169 (closed)
2. @soyuka pointed out correctly that the fixtures in core did have the space
3. Started digging through the the git log....
4. Turns out the space was had actually been removed in the ORM annotations generator fc74945 making the produced files not in line with the core anymore

Solution

1. Re-added the space to the annotations generator, just like how it worked before. This way I didn't "fix" by adapting the tests, and it should be an actual fix now.
2. Added the space in expected e2e entities file which means these are now in line with the fixtures in core, so imho they should be with the space.
