[⚡esl-animate]: intergaration/unit tests coverage for esl-animate module parts

[ala-n]

As an ESL architect, I want to have modules covered by integration/unit tests to detect basic gups in case of global or module updates,

Scope: Tess should cover the following areas of module:

• ESL Animate Service smoke (basic + options)
• ESL Animate Element unit (wrapper) tests
• ESL Animate Mixin unit (wrapper) tests
