Update SDK functions which upload files

[sarora180673]

Issue observed with functions which upload file e.g., setAppLogo

When we call /api/settings/appLogo endpoint, we specify
logoImage and target in Request Body and it works fine.

While setAppLogoParams has only logoImage

async setAppLogo(params: SetAppLogoParams) : Promise {
return this.apiCall('appLogo', params, {}, Methods.post);
}

export interface SetAppLogoParams {
logoImage: File;
}
