Latest version of tinyspy (3.0.1) causes a Cannot redefine property: mock when trying to spyOn an object multiple times

[vladfrangu]

Describe the bug

Renovate caught this issue in our CI (apify/apify-cli#636). It seems like the latest version of tinyspy (3.0.1) causes some issues when trying to spy on and mock an object's method multiple times. This issue doesn't repro on tinyspy 3.0.0 (and somehow I was also unable to reproduce this with tinyspy directly...)

Yup, getting this in my ci too. Typescript's intellisense also doesn't pickup import

Reverted the change in [email protected], so renovate shouldn't pick it up again. The change instead will be published as 4.0.0.
