* enhance: add statusline test module

* update old tests to use statusline test setup

* show diff in statusline:expect

* Revert "show diff in statusline:expect"

This reverts commit cea25185fde1b99110759f198ef1fc724626306c.

* autoformat

* fix testcov reports

* update statusline test module

* revert lualine_spec

* update lualine_spec using statusline module

* apply formater

* add tabline support to statusline test module

* re enable tabline tests

* fix inconsistency in buffers mode test due to bufnr changing

Should we be showing bufnr/buffer_position in buffers component

* autoformat

* minor tweeks to stl test module

* use nvim_eval_statusline in nvim-0.6+

* fix tabs component on nvim-0.5

* enable disabled branch test

--- ## Testing module for lualines statusline
---
--- ###Uses:
---
--- Create a new instence with status width 120 & for active statusline
--- like following.
---
--- ``lua
--- local statusline = require('tests.statusline').new(120, 'active')
--- ```
---
--- To create a new instence with status width 80 & for inactive statusline use following.
---
--- ``lua
--- local statusline = require('tests.statusline').new(120, 'inactive')
--- ```
---
--- Now setup the state you want to test.
--- To test you'll call `expect` pmethod on statusline for example.
---
--- To create a new instence with status width 80 & tabline
---
--- ``lua
--- local statusline = require('tests.statusline').new(120, 'tabline')
--- ```
---
--- Now setup the state you want to test.
--- To test you'll call `expect` method on statusline for example.
---
--- ``lua
--- statusline:expect([===[
--- highlights = {

--- }
--- |{1: [No Name] }
--- {1: }
--- {1: 0:1 }|
---
---]===])
--- ```
---
--- For more flexibility you can match a patten in expect block.
--- ``lua

---
--- An easy way to create an expect block is to call `snapshot` method
--- on statusline where you'll call expect and run the test. It will print
--- an expect block based on the state of statusline. You can copy it and
--- replace the snapshot call with the expect call.
