Vars defined on request level returns with different datatype in Safe and Dev mode

[SPIRIT-00]

I have checked the following:

• [X] I use the newest version of bruno.
• [X] I've searched existing issues and found nothing related to my issue.

Describe the bug

null and boolean values return as string in safe mode.

Unexpected behavior, it may cause incorrect scripts work.

.bru file to reproduce the bug

meta { name: DataType type: http seq: 1 }
