Migration to Angular 5 - No provider for HttpClient error

[Herzenkin]

After migration to Angular 5 all tests with FakeBackend usages fail with next errors:

Error: StaticInjectorError[HttpClient]: StaticInjectorError[HttpClient]: NullInjectorError: No provider for HttpClient! at _NullInjector.webpackJsonp.../../../core/esm5/core.js._NullInjector.get .../node_modules/@angular/core/esm5/core.js:923:1) at resolveToken .../node_modules/@angular/core/esm5/core.js:1211:1) at tryResolveToken .../node_modules/@angular/core/esm5/core.js:1153:1) at StaticInjector.webpackJsonp.../../../core/esm5/core.js.StaticInjector.get .../node_modules/@angular/core/esm5/core.js:1024:1) at resolveToken .../node_modules/@angular/core/esm5/core.js:1211:1) at tryResolveToken.../node_modules/@angular/core/esm5/core.js:1153:1) at StaticInjector.webpackJsonp.../../../core/esm5/core.js.StaticInjector.get .../node_modules/@angular/core/esm5/core.js:1024:1) at resolveNgModuleDep .../node_modules/@angular/core/esm5/core.js:10585:1) at _createClass .../node_modules/@angular/core/esm5/core.js:10622:1) at _createProviderInstance$1 .../node_modules/@angular/core/esm5/core.js:10596:1)

The solution of similar issue doesn't help.

Any suggestions?

UPD: changed all instances of deprecated "http" service with new "httpClient" one.

BTW, are you gonna update dev dependencies fro this project?
