InterstitialAd.isLoaded return an object instead of Promise<boolean> admob-plus-cordova 2.0.0-alpha.13

[LHLK]

Describe the bug
I used to execute InterstitialAd.isLoaded checking whether or not the InterstitialAd was loaded without any issues. Recently, after upgrade to the latest version admob-plus-cordova 2.0.0-alpha.13 the isLoaded() return an object instead. So how do I check if the InterstitialAd is loaded or not ? Return objects are as follows:
__zone_symbol__state
: null
__zone_symbol__value
: Array(4)
0:
v {_parent: v, _name: 'angular', _properties: {…}, _zoneDelegate: v}
1:
l {__zone_symbol__state: null, __zone_symbol__value: Array(0)}
2:
Z=> {…}
3: undefined
length: 4
[[Prototype]]
:
Array(0)
Symbol(Symbol.species)
:
(...)
Symbol(Symbol.toStringTag)
:
(...)
[[Prototype]]: Object

To Reproduce
Steps to reproduce the behavior:

1. Go to '...'
2. Click on '....'
3. Scroll down to '....'
4. See error

Expected behavior
InterstitialAd.isLoaded should return Promise as the previous version
