REPL: can't import plugin and use it

[SuperFola]

Describe the bug It seems like when we import a plugin in the REPL and then try to run one of its function, it's deleted before running the function.

To Reproduce Steps to reproduce the behavior:

1. Compile arkscript and the console module
2. Run build/arkscript
3. Type (import "console.arkm") in the REPL, then hit enter ; type (console:clear) and hit enter
4. See error

Expected behavior The functions of the imported modules should stay imported.

Code or Screenshots

ArkScript version or commit hash 3.1.1
